To all whom it may concern;

Be it known that I, MONTGOMERY WADDELI 'a subject' of the King of Great Britain, and a resident of New 'York, county and State of New York, United States of America, have invented certain new and useful Improvements in Machines for Twisting Together the Filaments of a Thread of Artificial Silk or clear, and exact description.

My invention relates to machines \upon which threads composed of a plurality of untwisted and substantially parallel filaments of artificial silk, br

Similar Material, of which the following is a full,

' like material, are spun or twisted together to formidatwisted thread. In this class of machines it is de sirable to deliver the untwisted threads to the. twist,- ing mechanism, directly from the bodies upon which the filaments are wound when they emerge from the coagulating or fixing bath, and upon which they are treated during the various steps of the process'of forming the same prior to' that of spinning.

One of the objects of the prcsent invention is to provide a machine upon which a thread of artificial silk or similar material may be twisted directly or spun from the bodies upon which they were originally wound.

A further object of my invention is to providea means for positively rotating said bodies in order to deliver the untwisted threads wound thereupon to the twisting mechanism.

A further object of my invention is to provide a machine of the character above referred to, with a means for simultaneously stopping the rotation of the said bodies and of the twisting spindleor flier whenever it is necessary to interruptthe twisting operation, as for instance, upon more filaments. I Further objects of my invention will appear in the accompanying specification and claims.)

In the drawings, forming a part of this specification, Figure l is a front elevational view of a portion of a spinningframe embodying my'invention; Fig. 2

v i is a transverse sectional view of my improved masimilarly arranged rollers 5-5, which are adapted to support between them the flanged "rings 6, upon 'which thethread composed of the untwisted and the breaking of one or substantially parallelfilaments is wound. The shafts 4- -4 carrying the rollers' 55 are positively rotated in the same direction by any suitable means, and by their rotation impart a rotary motion to the flanged rings 6 supported thereon. These flanged rings 6 are the bodies upon which the untwisted filaments are wound as they are formed in the fixing bath, and upon which they .are subjected to the subsequent steps of the process of making artificial silk or similar material prior to the step of twisting the filaments together. Within the frame 1 of the twisting ma chine is the usual drum or tin roller 7, by which the spindles 88, arranged in series along each side of the frame 1, are revolved through the belts 9' and 'are supported in suitable rails 11, 12, the upper of which 11 is provided with a suitable bearing bushing 11, and the lower ofwhich' is provided with a suitable step bearing 12. The upper end of each spindle'carries a flier 13, and loosely mounted upon the spindle are) bobbins 14 upon which .the threadiswound, as it is twisted. 15 indicates the builder rail, which is given, by any suitable mechanism, a reciprocatory motion par allel to the spindle and to the bobbins 14 carried,;;

thereon, to wind the'thread in regular courses upon the bobbins.

16 indicates the thread board through the guide eye 16 in which the thread passes, as it is delivered from the flanged ring 6 to the end of the flier 13. I prefer, however, to make the eye 16 in the thread board of such a size as'will permit the twist imparted to the thread by the rotation of the flier to extndnpward through thethread board to the point ofidelivery of the thread fi'om the surface of the ring in orderto catch Gmd bind in to the twisted thread any broken filzfment which otherwise would wind. up and accumulate on.

the ring and eventually break the thread. 17 indicates a rod, the upper end of-whieh is mounts ed in a bushing-18 in the top 2 of the frame, and the lower end of which is pivoted at 19 to a foot lever 20,- ,which, tiu'n, is pivoted'on a shaft 21, secured to and extending lengthwise of the frame 1. The upperend' of the rod 17 carries. a yoke 22, the upper ends of which are provided with shoes 23 arranged opposite the flanges of each ring. The shoes 23 may have their concave sides covered with leather, or any other suitable material, which will not injure or wear the enamel or protective coating from the flanges of said rings. Ar-

ranged in a suitable position between the ends of the" rod 17 is a collar 24 which is adapted to engage the in- .ner end of a lever 25 pivoted to the frame on the shaft 26, said lever carrying at its outer end a brake shoe 27 adapted to be brought into Contact with the upper surface of the whirl 1.0, when the vtoot lever 20 is de pressed.

The operation of my device is as follows: The parts being in the position shown at the left hand side of Fig. 2, that is to say, with the foot lever 20 depressed and the brake 27 forced against the whirl 10, the flanged ring 6 is placed between the rollers'5 and upon the shoes 23 carried by the yoke 22. The thread is led through the eye 16 of the thread board, and through the flier 13 to the bobbin 14, the shafts 4-4 and the tin roller 7 being positively rotated from any suitable source of power. After the thread has been attached to the bobbin, the foot is lifted from the foot lever 20. and the rod 1.7 is permitted to all to the position shown at the right hand side of Fig. 2, whereupon the bral re is removed irom'the whirl 10, and the ring 6 is' allowed to drop and to,be positively rotated by the contact of its flanges upon the rollers 5-5 carried by the shafts 44. The untwisted threads will then be delivered directly from the rotating rings '6 through the guide eye 16 to the flier 13, which, being positiuely rotated, will impart a twist to the thread between the end of the flier and the point where the thread leaves the ring. The rotation of the flier will drag the bobbin 14 around the spindle 8, and the builder rail 15'will impart to the bobbin a vertically. rociprooatory motion, as a result of which. the twisted thread will be wound in regular courses upon the bobbin. Ii, for any reason, as ior instance, the breaking of one or more of the filaments composing the,thread, it should be desirable to discontinue the operation of twisting, it is merely necessary to depress the foot lever 20, whereupon the brake 27 will be brought into contact with the whirl 10 on the spindle 8, and at the same time the ring 6 will be liited by the yoke 22 out of contact with the driving rollers 5,

thus simultaneously stopping the rotation of both the spindle andthe flanged rings. 1

While I have described and illustrated one form of my invention, it is to be understood that other forms may be employed without departing from the spirit of my invention, since iny invention contemplates the embodiment in any spinningor twisting frame of a v mechanism for spinning and imparting a twist to a thread composed of untwisted and substantially parallel filaments oi artificial silk, or similar material, as the same are delivered directly from the bodies upon which they are wound when first formed, and upon which they are subjected to the subsequent, steps of washing, drying, and bleaching, preparatory to forming the same into a twisted thread of artificial silk.

Having thus described my invention,'what -I claim and desire to protect by Letters Patent of'the United States, is:- p
